HAND-POWER LIFTING AND FORCE PUMP.

SPECIFICATION forming part of Letters Patent NO. 303,038, dated August 5,1884.

To all whom it may concern Be it known that I, OLOF Prrrnnson, of New Boston, in the county of Mercer and State of Illinois, have invented an Improved Hand- Power Lifting and Force Pump, of which the followingis a full, clear, and exact description.

lfhe purpose of my improvements is to facilitate the raising of water from any depth by reducing the force required; and, further, to reduce the wear consequeut upon working and the amount of attention necessary to maintain a working eificiency. I effect a successful realization of these objects in the following manner, reference being had to the accompanying drawing, forming part of this specification, in which the figure represents a pump in vertical cross-section.

H is the standard or upper visible portion of the pump, which forms a support for the lower portion or working pumpbarrel, airr-hamber, 8rd, attached to the standard H by the water-pipe d, which conveys the pumped water to the discharge-spoutG, formed on the standard H.

g is a cap fastened upon standard H, and supporting the pump-handle F at either of the points f f f upon the pin f, passing through a slotted upper extension of cap 9, whereby the handle F may be shifted in order that its weight on one side of the pin f, primarily balancing that of the plunger-rod e and piston E, on the other side of the said pivot f, shall also add weight to or subtract it from rod 6 and piston E, to enable them toexactly balance the column of water in the pipe d, sufficient weight being added to handle F and plungerrod e, proportionate to the weight of the water-tube d, as said tube may be varied in length for different positions to accomplish this object.

e represents a guide for the plunger-rod 6,

extended to it from the water-pipe d.

The pump -piston E is constructed with dished or concave sides and concave .top and bottom, leaving a'lip, a", at each end closely fitting the interior of the pump-barrel A, and expanding against it in. working by the resistance of the water to the strokes of the piston E, thereby producing a tight working fit be tween the elastic pistolrlip 2 and the pump- Application filed October 19, 1883. (No model.)

barrel A. A space, j, is formed between the lip i, the concave sides of piston E, and the interior of pump-barrel A, which, when filled by water percolating past the piston-lip 2', acts as a fluid-packing chamber, whose contents further perfect the working fit of piston E in pump-barrel A.

a a represent holes in the closed foot of'working-barrel A, for the admission of water to the valve 0 and its seat B, the valve being weighted at the point, as shown at c.

At D is shown the air or discharge cham her, having a cap, d, which is pierced for the lower end of pipe (1, which descends into the discharge-chamber D, nearly to the valve-seat B of the outletvalve O. The space between the cap (I and the lower end of water-pipe d forms an air-space or spring to maintain an equal and steady flow of water between the strokes of piston E. The valve 0 is also weighted at c.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In a pump, the combination, with the standard H, of the piston-chamber A, provided with the weighted valve 0, and the air-chamber D, communicating with the piston-chain her, and provided with the weighted valve 0, substantially as herein shown and described.

2. In a pump, the combination, with the standard II, the pipe (2, and the handle 1?, of 80 the piston-cylinder A, provided with the valve G, the air-chamber D, communicating with the piston-chamber, and provided'with the valve 0, and the piston E, connected by rod 6 with the said handle, substantially as herein shown and described.

3. I In a pump, the combination, with the standard H and piston-cylinder A, of the airchamber D, provided with thevalve G, and the pipe d, extending from the standard to and within the air-chamber nearly to its valve-seat, substantially as herein shown and described, and for the purpose set forth.

OLOF PATTERSON.
